CHRISTIAN FRIEDRICH MAX KROENERT, OF ALTONA, GERMANY.

MACHINE FOR PRINTING TAPESTRY.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed July 30. 1907. $erial No. 386201- T 0 all whom it may concern:

Be it known that I, CHRISTIAN FRIEDRICH MAX KROENERT, a subject of the German Emperor, and a resident of Altona, Germany, have invented certain new and useful l mprovements in Machines for Printing Tapestry, of which the following is a specification.

In machines for printing tapestry as hitherto constructed, in which the bearings of the color mechanism and of the pattern roller are mounted on carriages adjustable relatively to each other, it is necessary in altering the color mechanism to adjust the rollers of the ink applying device by means of pressure spindles in order to admit of insorting a pattern roller of larger or smaller diameter, and the color cloth had to be stretched over the pattern roller to enable the latter to apply the color to the fabric. These several special movements of the spindles for adjusting the pattern roller and the color cloth are replaced in accordance with the present invention by a lever movement, the carriages of the color applying device and of the pattern roller effecting a displacement of the color applying device and of the pattern roller in the ratio of 2 to l by the intermediary of gears upon actuation of the hand lever, thereby largely economizing time.

The sizecolor, printing machine, color mechanism in accordance with the present invention is illustrated in the accompanying drawing, in which v Figure 1 shows the color mechanism in side elevation with the smallest pattern roller inserted. Fig.2 represents the color mechanism in side elevation with the largest pattern roller inserted. Fig. 3 shows the color mechanism in section on the line AB of Fig. 1. Fig. 4 shows the color mechanism in top view, and Fig. 5 shows this mechanism in front elevation.

In the drawings a designates the counter pressure roller (pressure cylinder), 6, b the lateral frame of the machine to which the color mechanism arms 0, c are fixed. In the upper carriage of the color mechanism arms 0, c, the pressure spindle carriage d, d with the pattern roller bearings e, c, and the carriage f, f, with the racks g, g, are mounted they are connected with the spindles 7L, h, by means of the rings i, i.

In the lower carriage of the color-mechanism arms 0, c, the lateral members 75, 7c, receiving the guide rollers, Z, m, 7L, 0, for the color cloth 8, are mounted. These lateral members 7c, 7c, are provided with racks p; g is the color applying roller, 7" the color box and s the color cloth, which transfers the color from the application roller on to the pattern roller if, being driven through the gear wheels at, o, to which transmit motion to roller n.

The spindles '7, 7 serve for centering thecolor cloth 5. The rack g of the upper carriage for the pattern roller bearings e, e, and the rack p of the lower carriage for the color cloth 3, mesh with gear wheels 2 and 5 respectively. Fast on the same axis with wheel 2, is a wheel 3, while fast on the same axis with wheel 5, is a wheel 4. Wheels 3 and 4 are engaged by a common toothed sector y with which the hand lever r is connected. This hand lever, rotatable around the shaft 6, is provided in the known manner with a locking bolt z which may be caused to engage with the various notches 1, 1 ar ranged on the edge of a plate and indicated by a scale. The gear wheels 2 and 3, and 4, 5 present the ratio of 1 to 2, so that the carriages for the pattern roller and the color cloth are displaced relatively to the counter pressure roller in the ratio of 2 to 1 by the actuation of the hand lever, when a pattern roller is changed. For example, if the color mechanism is provided with a pattern roller 100 mm. in diameter, and if it is desired to replace this by a roller 200 mm. in diameter, the latter must be displaced by the half diameter, that is to say 50 mm., and the color applying means by the whole diameter, that is to say 100 mm. so that the pattern roller may bear snugly on the coun ter pressure roller (1 and on the color cloth 8.

The alteration of the color mechanism is effected in the following manner :The looking bolt 2 is released, the hand lever or displaced by the amount called for by the diameter of the pattern roller to be used. During this movement the crown of the actuating wheel y adjusts the wheels 3, 2, and these by means of the rack g adjust the pressure spindle carriage for the pattern roller bearings c, e. Similarly, the wheels 5, 4 are adjusted and they by means of the rack p adjust the lateral members 7c, is with the guide rollers Z, 'm, n, 0 for the color cloth, and consequently the entire color applying mechanism. The color applying mechanism and the pattern roller are also adjustable relatively to each other by means of'thespindles h, h and 7, 7 in the known manner.

What I claim is 1'- A device of the character described, com prising a first carriage, a pattern roller journaled therein, a second carriage, a color cloth carried thereby and engaging the attern roller, a lever, and gears intermediate said lever and carriages for simultaneously 10 shifting the first and second carriages at the ratio of one to two, substantially as specified. Signed by me at Hamburg, Germany this 18th day of July 1907.
